Thinking Machines Lab ships its first model, Inkling — and it's open-weight
3 minThinking Machines Lab, founded by former OpenAI CTO Mira Murati, released its first in-house model, Inkling — a mixture-of-experts system with 975 billion total parameters that activates only about 41 billion for any given task. Unlike the flagship models from OpenAI, Anthropic, or Google, it's released open-weight, so outside developers can download and modify it directly. The choice reinforces the company's stated bet against "one-size-fits-all" frontier models in favor of something the community can adapt.
